• Is keratoconus a refractive error?

  Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. This cone shape deflects light as it enters the eye on its way to the light-sensitive retina, causing distorted vision. There are several factors that cause Keratoconus: an imbalance of enzymes within the cornea, overexposure to ultraviolet rays from the sun, excessive eye rubbing, a history of poorly fitted contact lenses and chronic eye irritation.Keratoconus can result in nearsightedness and/or astigmatism, those are all refractice errors. Eyeglasses cannot help to patient with keratoconus, but contact lenses can. Learn more at http://www.allaboutvision.com/conditions/keratoconus.htm

• How can I repair the broken arm in glasses?

  In most cases, the broken arm may be caused by the missing of screws. A replacement screw will fix the problem. You may go to the local optical store and ask the workers to fix the right screw for your frames. If the screw on your frames become loose, you can use a screw driver to tighten it. If the arms of your frame is broken off, you may repair broken frames at the temples by using hot glue (for plastic frames) - boiling water and pins. Alternatively, replace the temple piece with a piece from another set of glasses. Unscrew the hinges and screw the new temple piece into position.

  Computer glasses are special glasses prescribed to lessen the symptoms associated with computer vision syndrome (CVS). CVS describes a group of symptoms caused by prolonged computer use. Symptoms appear because the eyes and brain react differently to words on a computer screen than they do to printed text. Symptoms often include eyestrain, dry eyes, headaches and blurred vision. Many people try to compensate for these vision problems by leaning forward or by looking down to see through the bottom portion of their glasses, often resulting in back and shoulder pain.

  Some people wear sunglasses or polarized glasses to reduce glare when they drive at night. I am not sure whether they do work well.

• How does eyeglasses correct vision problem?

  Eye glasses work in the same manner whether they are for nearsightedness or farsightedness. The eye glass lens is curved so that it bends the light rays that hit your eyes so you can see images clearly. Nearsighted individuals cannot clearly see things that are distant. This happens because the light rays come into focus in front of the retina. Farsighted individuals have the opposite problem. The shape of their eyes causes the light rays to come into focus behind the retina, causing things that are near to them to be out of focus. Some people have blurry vision due to an astigmatism, or a condition where the curvature of the eye is irregular, creating a second focal point within the eye. All three of these common problems can be corrected with glasses. Source:http://www.glassescrafter.com/information/how-glasses-correct-vision.html
